In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in, the several views:Figure 1 is a rear view of the printing frame with parts broken away tomore clearly illustrate the invention. Fig. 2 is a detail section takenon the line 2-2 of Fig. 1. Fig. 3 is a view of the reducing memberdetached.

The frame consists of side bars 1 and 2 which are connected to eachother by end bars 3. The said bars are rabbeted upon their inner facesto form a shoulder 4 upon which the photographic plate may be mounted,and upon which may also be mounted the rabbeted edge portion 5 of myimproved removable plate supporting member 6. The frame is provided withthe usual back member or compressing head 9 which is provided withspring means 10 adapted for engagement with the side bars of the frameso that aphotographic plate when placed in its operative position in theframe can be effectively retained therein.

The reducing member consists of a plurality of right angularly disposedarms 11 and 12, the outer edge portion of the arms 11 and 12 beingformed with shoulders 13 adapted to engage the shoulder 4 of the framebars. The inner edges of the arms 11 and 12 are provided with plateseats 14 and the terminals of said arms are provided with shoulders 13which are adapted to engage the shoulders of the side bars 1 and 2 ofthe photographic frame.
